Overview
The OPTIFLUX 4400 electromagnetic flowmeter (EMF) is developed in accordance with IEC 61508 for safety-related applications up to safety integrity level (SIL) 2/3. It features automated partial proof testing capabilities, which allows to extend the time interval between full proof tests and increase plant uptime in safety instrumented systems (SIS).
- Automated partial proof testing capability for extended full proof test intervals
- Integrated conductivity measurement
- Enhanced diagnostic package:
- Compliant with NAMUR NE 107
- Diagnostic test interval incl. fault response time of only 2 minutes: alert issued if meter runs out of spec
- Detects gas bubbles, solids, electrode corrosion and deposits on the electrodes, conductivity changes, an empty or partially filled pipe, a disturbed flow profile, external magnetic fields, etc.
- Redundant data storage
- Real-time clock for logging events
- User-friendly coloured display for status indication
- Ease of installation and device set-up:
- Optimised device menu: reduced menu items for quick commissioning
- Available with patented "virtual reference" option: cost-saving installation without grounding rings (in non-SIL applications)
- High measuring accuracy and long-term stability: measuring error of only ±0.2% of measured value ±1 mm/s
- Wide range of liner and electrode materials
- Approved for use in hazardous areas: ATEX, IECEx db eb
- Field device verification of flowmeter with the OPTICHECK Master and OPTICHECK DTM service tools, e.g. for partial proof test documentation acc. to IEC 61508
